Summary
- A six-year-old Colorado girl is now cancer-free after an infant brainstem cancer diagnosis.
- Her tumor was an extremely rare, unique high-grade glioma, second of its kind at Children's Hospital Colorado.
- Precision medicine and genetic sequencing led to a tailored treatment, defying initial grim prognoses.

A six-year-old girl from Colorado is now cancer-free after a remarkable battle with an exceptionally rare and aggressive brainstem cancer. Hadley McMahon was diagnosed with an infant high-grade glioma, a unique and aggressive brain tumor, when she was just a few months old. Her specific tumor genetics were so unusual that it placed her among a handful of cases worldwide.
The tumor's location on the brainstem presented significant challenges for treatment, and doctors initially had a devastating outlook. Facing uncharted territory, Hadley's medical team and family embarked on a treatment journey that involved a brain biopsy and chemotherapy. This pioneering approach was guided by advanced genetic sequencing.
Through personalized medicine and months of intensive treatment, Hadley began to defy expectations. By the five-year mark after her diagnosis, she was declared cancer-free. Today, she enjoys a normal childhood, attending school and playing with her older brother.
Hadley's survival and recovery are not only a personal triumph but also a beacon of hope for other children facing similar rare cancers. Her case highlights the progress in medical research, genetic testing, and personalized treatments, offering future patients a more hopeful prognosis and potentially new answers.
